Structure Activity Relationship Study of Diimine Pt^II Catalysts for H/D Exchange

Abstract

This report describes a comparison of the reactivity of a series of diimine PtII complexes as catalysts for H/D exchange between benzene and RCO2D. Substitution at the 2- and 6-positions of the N-aryl group and especially incorporation of halogens at these sites lead to significant increases in catalyst reactivity. Interestingly, marked differences in the structure activity relationship were observed in this catalytic study compared to previously reported stoichiometric investigations of C–H activation at PtII diimine complexes.
